Title:

Liquid crystal display element

Document Type and Number:

Japanese Patent JP6358489

Kind Code:

B2

Abstract:

The liquid crystal display element includes: two transparent substrates; a liquid crystal composition sandwiched between the two transparent substrates and containing one or two or more liquid crystal compounds; and a polymer or copolymer that is included in the liquid crystal composition, the polymer or copolymer being a cured product of a polymerizable composition that contains one or two or more polymerizable compounds and a photopolymerization initiator having a maximum absorption wavelength peak at 310 nm to 380 nm. The content of the polymerizable composition is 1% by mass or more and less than 40% by mass based on the total weight of the polymerizable composition and the liquid crystal composition.
